Fossil fuels are non-renewable resources that are extracted from the earth and then burned to create energy. They are primarily made of carbon and are formed from the transformation of ancient plants and animals through pressure and temperature over millions of years. This process essentially stores the sun's energy over time, and the resulting fuels allow the use of more energy than today's photosynthesis could provide. The sun's energy is captured by plants through photosynthesis, and animals rely on these plants for food. Thus, the energy in fossil fuels can be traced back to the sun. Fossil fuels have been a significant contributor to global climate change, accounting for a large portion of greenhouse gas emissions and carbon dioxide emissions. As a result, there is a growing shift towards renewable energy sources such as solar power, which harnesses the sun's energy to create a cleaner and more sustainable form of energy.

What You'll Learn
Fossil fuels are formed from the transformation of ancient plants
Terrestrial plants tend to form coal and methane. Coal fields, for example, date back to the Carboniferous period of Earth's history. Plants also form type III kerogen, a source of natural gas. As the fossil material gets buried deeper and deeper underground, it is subjected to increased heat and pressure, which breaks down the fossil molecules. The transitional materials formed during this process include peat from plants and kerogen from plankton. These materials have less stored energy than fully formed fossil fuels and are considered "partial" fossil fuels.
After millions of years, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. These fossil fuels are then extracted through coal mining and the drilling of oil and gas wells on land and offshore.
The energy in fossil fuels comes from the sun, which drives photosynthesis in plants. Plants convert solar energy into biomass through the process of photosynthesis, and this biomass was burned by early humans for heat and light. Fossil fuels essentially store the sun's energy over time, and their discovery allowed humanity to use more energy than photosynthesis could provide at the time.

Solar energy is collected through photovoltaic (PV) panels
Fossil fuels are non-renewable resources that include oil, coal, and natural gas. They are extracted from the earth and burned to create energy. However, they contribute to climate change by increasing carbon emissions and contaminating water sources. In contrast, solar energy is a renewable resource that uses photovoltaic (PV) panels to collect and convert sunlight into electrical energy.
Photovoltaic (PV) panels are an essential component of solar energy systems, and they play a crucial role in harnessing the power of the sun to generate clean and sustainable electricity. PV panels are composed of PV cells, which are non-mechanical devices made of semiconductor materials, typically including silicon. These cells are designed to convert sunlight directly into electricity by absorbing photons, or particles of solar energy. The absorbed photons dislodge electrons from the atoms of the semiconductor material, creating electrical charges that flow as electricity. PV panels can be installed on rooftops or ground mounts, making them accessible to both residential and commercial properties.
PV panels can be grouped into arrays of different sizes to increase their electricity-generating capacity. These arrays can range from a few panels to hundreds, depending on the energy requirements. Additionally, PV systems may include mounting structures that orient the panels toward the sun to optimize energy production. The electricity generated by PV panels is in the form of direct current (DC), which can be converted into alternating current (AC) through devices called inverters. AC electricity is then used to power appliances in homes and businesses.
The efficiency of PV panels has significantly improved over the years, with the average efficiency increasing from less than 10% in the mid-1980s to around 15% by 2015. Researchers continue to work on enhancing PV efficiency to make solar energy even more cost-competitive with conventional energy sources. The cost of installing solar panels has been a concern for many, as it can be significantly higher than simply paying utility companies for fossil fuel-based energy. However, the long-term savings, tax credits, and the use of clean energy sources make solar energy an attractive option for those willing to make the initial investment.
In summary, solar energy is collected through photovoltaic (PV) panels that convert sunlight into electrical energy. PV panels have become more efficient and accessible, contributing to the growing adoption of renewable energy sources. While there are challenges and considerations, such as cost and efficiency, the benefits of solar energy, including its environmental advantages over fossil fuels, make it a promising direction for a low-carbon future.

Fossil fuels contribute to climate change
Fossil fuels are ultimately of solar origin, having formed from the transformation of ancient plants under pressure and temperature over millions of years. This process essentially stores the sun's energy over time, and the resulting fuels can be burned to create energy. However, the burning of fossil fuels releases greenhouse gases, such as carbon dioxide, nitrous oxide, and soot, into the atmosphere, contributing to climate change.
The greenhouse effect caused by these emissions leads to a net warming of the Earth's atmosphere, as the cooling effect of airborne particles is small compared to the heating caused by the greenhouse effect. The increased atmospheric temperatures have far-reaching effects on ecosystems and human health, with the ocean absorbing most of the heat. As the ocean warms, its volume increases, causing global sea levels to rise. This, in turn, leads to more frequent flooding, destructive storm surges, and saltwater intrusion, threatening coastal communities.
In addition to the direct impact on sea levels, climate change caused by fossil fuel emissions also contributes to ocean acidification. The increased acidity makes it harder for marine organisms to build shells and coral skeletons, posing threats to coral reefs, fishing, tourism, and the economy. The warming ocean waters also disrupt food supplies, as herding, hunting, and fishing are impacted.
Furthermore, the burning of fossil fuels has led to a rise in extreme weather events, including forest fires, invasive pests, and diseases. These events have caused billions of dollars in damage and contributed to a global rise in hunger and poor nutrition as fisheries, crops, and livestock are destroyed or become less productive.
The extraction and use of fossil fuels also have indirect impacts on the environment. Companies that extract fossil fuels often take over large areas of land for drilling and mining, leaving the environment barren and inhospitable. The process of drilling degrades and erodes the ground and pollutes water supplies, further harming ecosystems and human access to clean water.

Fossil fuels degrade and erode the ground
Fossil fuels are ultimately of solar origin. Fossil fuels are formed from the transformation of ancient plants and animals through pressure and temperature over millions of years. This process essentially stores the sun's energy over time, resulting in fuels such as coal, oil, and natural gas.
However, the extraction and use of fossil fuels have significant environmental impacts, including the degradation and erosion of the ground. Mining, drilling, and burning fossil fuels can have detrimental effects on the environment and human health. One of the ways in which fossil fuels degrade and erode the ground is through the process of drilling and mining. Companies that extract fossil fuels often take over large areas of land for drilling and mining activities. For example, strip mining involves scraping and blasting entire swaths of terrain, including forests and mountaintops, to access coal or oil deposits. This process not only removes valuable ecosystems but also leaves the land barren and inhospitable.
The drilling and extraction processes can also contaminate groundwater and drinking water sources. For instance, fracking, a method used to extract previously inaccessible oil reserves, can result in toxic wastewater that contains substances like arsenic, lead, chlorine, and mercury, which can contaminate water supplies. Oil spills, which can occur during extraction, transportation, or refining, can also have devastating effects on the environment, harming wildlife, destroying habitats, and polluting water sources.
In addition to the direct impacts on the ground, the burning of fossil fuels contributes to global warming and climate change. The carbon dioxide emitted during combustion has been linked to rising global temperatures, leading to extreme weather events, sea level rise, and other consequences. These climate change impacts further exacerbate the degradation and erosion of the ground, as increased frequencies of extreme weather events, such as hurricanes, floods, and droughts, can cause soil erosion and damage to landscapes.
The use of fossil fuels also has indirect effects on the ground and the environment. The infrastructure required for fossil fuel extraction, processing, and transportation, such as wells, pipelines, access roads, and waste disposal facilities, can fragment critical wildlife habitats and disrupt ecosystems. Additionally, the high carbon content of fossil fuels contributes to increased carbon emissions, further exacerbating climate change and its impacts on the environment.

Solar energy is more expensive than fossil fuels
Fossil fuels are non-renewable resources that are extracted from the earth and then burned to create energy. Oil, coal, and natural gas are examples of fossil fuels that power most of the planet. In 2023, 60% of the American nation's energy came from fossil fuels. These resources are not infinite, but they are plentiful, and the technology to extract them is constantly improving, making them more and more economical to produce and use.
Solar energy, on the other hand, is a renewable energy source that uses the power of the sun to create energy. This energy is collected through photovoltaic (PV) panels and can be temporarily stored in solar batteries. Solar panels can be installed almost anywhere, from rooftops to fields, and they are becoming more advanced and affordable.
While solar energy has numerous benefits, such as being a clean and endless source of energy, the main discussion around solar energy vs. fossil fuels often revolves around cost. Solar energy has been more expensive than fossil fuels due to several factors. Firstly, the intermittent nature of sunshine makes it challenging to match electricity supply and demand moment-to-moment, unlike fossil fuels, which offer near-constant availability. This "on-demand" reliability of fossil fuels is a significant advantage in terms of their application.
Secondly, government subsidies play a crucial role in shaping the growth potential of energy sources. The G20 nations, which account for over 85% of global GDP, have been spending $452 billion annually to subsidize fossil fuels. This subsidization keeps the costs of fossil fuels low compared to solar energy, which has also received subsidies but at a lower rate.
Thirdly, the cost of installing solar panels can be high, ranging from $14,000 to $21,000 on average for residential properties in 2024. This upfront investment is a significant barrier for many, especially when compared to the relatively low monthly costs of continuing to use fossil fuels. However, it is important to note that solar panels can last for decades, resulting in long-term savings that can outweigh the initial costs.
In conclusion, while solar energy has quickly caught up in terms of cost with its non-renewable counterparts, the higher upfront costs, the intermittent nature of sunshine, and the subsidization of fossil fuels have contributed to solar energy being more expensive than fossil fuels. However, with the negative environmental impacts of fossil fuels and the improving accessibility of solar energy, the renewable resource is expected to play a significant role in driving the adoption of renewable resources in the future.
